Barnstead/Lab-Line Multi-Blok* Heat Blocks

The interchangeable block design allows for different size test tubes to be heated by simply changing the block. Blocks are purchased individually. The blocks a re made of solid black anodized aluminum to assure maximum heat transfer and to retain heat longer. Exceptional heat uniformity is further assured by the close contact of test tubes with the blockwalls. The interchangeable blocks accommodate all standard size test tubes and combination of sizes for a variety of lab uses. Individual tubes can be removed without disturbing test conditions. The solid block can be used as a temperature-controlled hot plate.
